Definitions

  • the invention relates to electromagnetic two-way valves.
  • a known electromagnetic two-way valve comprises a body, a clack carried with axial play by a mobile portion of, and a magnetic core movable under the effect of a magnetic field produced by an electrical winding to control movement of the mobile piece.
  • the clack cooperates with a seat disposed between an inlet and an outlet for fluid to be controlled, and the mobile portion is movable in a chamber connected to the inlet by a restricted passage.
  • the clack has a hole situated facing the passage of the seat, and the mobile portion has, in cross-section, a greater area than the passage of the seat.
  • the mobile portion also has a portion which closes the hole of the clack in the closed position of the valve.
  • a separation between the inlet and said chamber is formed by a portion of the mobile portion exposed to the pressure in the inlet so that the fluid exerts on the mobile portion a thrust to assist its movement in the direction of opening of the clack as soon as the mobile portion is removed from the hole of the clack.
  • a valve of this type is, for example, described in Swiss Pat. No. 395,672.
  • An aim of the invention is to remedy this disadvantage by providing an arrangement which produces a relatively great assistance by fluid pressure during a first part of the opening movement, and a weak assistance in a second part.
  • the assistance means only produce a low resistance during the first part of the closing movement, which enables rapid closure.
  • the resistance of the assistance means becomes greater, but this does not delay closing by a great amount since, on the one hand, the clack may already be in the closed position and, on the other hand, the moving parts are already in motion.
  • This resistance of the assistance means serves to damp movement of the parts still in motion at the end of closing of the valve.
  • the restricted passage comprises an annular passage the inner circumference of which is defined by the mobile piece, and the valve is arranged so that movement of the mobile piece towards the open position of the valve produces an increase of the cross-sectional area of the restricted passage.
  • FIG. 1 is an axial cross-section of a first embodiment
  • FIGS. 2 and 3 show a part of FIG. 1 in two different positions of operation
  • FIG. 4 is an axial cross-section of a second embodiment
  • FIGS. 5 and 6 show a part of FIG. 4 in two different positions of operation.
  • the two-way valve shown in FIGS. 1 to 3 comprises a body 1 with an inlet 2 and an outlet 3.
  • the flow of fluid between this inlet and outlet is controlled by a clack 4 bearing on an annular seat 5 at the upper end of an axially extending valve seat portion having a central opening leading to outlet 3.
  • the electromagnetic part of the valve comprises a winding 6 mounted on a tube 7 of non-magnetic material fixed in a piece 8 screwed in body 1.
  • a fixed magnetic core 9 In the tube 7 are a fixed magnetic core 9 and a mobile magnetic core 10 carrying the clack 4 and submitted to the action of a spring 11 biasing it to apply the clack 4 against seat 5.
  • the mobile core 10 has two longitudinal grooves 12 to facilitate its movement in the fluid filling a chamber 13 in tube 7. These grooves 12 communicate with a housing 14 provided in a mobile portion at the lower end of the mobile core 10 and in which the clack 4 is floatably mounted.
  • the clack 4 has a central bleeder hole 15, and the top face of housing 14 in the mobile portion of the core 10 has an annular rib 16 seat portion which is able to bear against the clack 4 to obturate the hole 15. The diameter of rib 16 less than that of the circular seat 5.
  • annular membrane 17 is gripped by its outer edge between the piece 8 and body 1.
  • the inner edge of membrane 17 is free and, in the closed position of the valve, bears against the lower end of the mobile portion of core 10 so that the membrane 17 obturates the direct passage between the chamber 13 and a chamber 18 situated under membrane 17 and communicating with the inlet 2.
  • the chamber 13 is connected to the outlet 3, which is at a low pressure, and the pressure in chamber 13 drops rapidly, since the cross-sectional area of the hole 15 is considerably greater than the cross-sectional area of the fluid-passage between the chamber 18 and chamber 13.
  • the smallest section of this passage is determined either by the clearance between the outer wall of the seat 5 and the lower opening of housing 14, or by the clearance between the periphery of clack 4 and the lateral wall of housing 14.
  • the clack 4 In the second part of the upwards movement of mobile core 10, the clack 4 is lifted from the seat 5 by an annular flange 19 at the lower end of a flange portion 19' of the core 10.
  • the force required to lift the clack 4 is relatively weak, because at the moment when the clack 4 must be removed from seat 5, the difference of pressure between the chamber 13 and outlet 3 is relatively small.
  • communication between the chambers 13 and 18 is interrupted by contact of the flange 19 with clack 4, and the pressure in chamber 18 acts on all of the annular surface of the mobile parts external to the seat 5 (see FIG. 2).
  • FIG. 4 illustrates a second embodiment which is similar to the first and the same parts are designated by the same reference numerals.
  • the membrane 17 is dispensed with and fluid-tightness between the body 1 and piece 8 is provided by an annular joint 20.
  • Communication between the fluid inlet 2 and chamber 13 is made by two annular passages 21 and 22.
  • the passage 22 is formed by the clearance between the lower end of core 10 and an inwardly-protruding annular rib 23 on piece 8.
  • the cross-sectional area of this annular passage 22 varies as a function of the position of the mobile core 10; it increases as soon as the lower end of the core 10 has passed above rib 23.
  • the other passage 21 is formed, as in the first embodiment, by the clearance between the outer wall of seat 5 and the flange 19 of core 10.
  • Operation of the second embodiment of valve is similar to that of the first embodiment. From the beginning of lifting up of the core 10, the central hole 15 of the clack 4 is opened, which makes the pressure in chamber 13 drop by connecting it to the exhaust outlet 3.
  • the core 10 occupies the position shown in FIG. 5; this takes place just before the core 10 passes by the rib 23, when the section of the passage between the chambers 13 and 18 has its lesser value.
  • FIG. 6 shows the open position of the valve.
